Annexe or Static Caravan

We are a couple in our 40s who are looking for an Annexe or Static Caravan with either a barn or workshop to work in. One of us is self employed ( Carpenter/Prop Maker ) hence a barn or workshop and one is an Accounts Assistant. Currently living/looking after an elderly relative. We are looking to move out and rent while we consider our options on where to settle and find our forever home. We are a quite couple who respects other people and their privacy. We work all week and relax in the evenings and weekends.
